Africa is home to many disease outbreaks yet is ill-prepared to deal with them.
African leaders need to up their health allocations to help the new World Health Organisation Director-General meet his health care targets for the continent.

There's a new weapon against mosquitoes that spreads diseases such as dengue and yellow fever – more mosquitoes.
Cages full of hand reared yellow fever mosquitoes await research (or possibly release)

Upscaling the success of emerging mosquito control technologies relies on automating the rearing and release of millions of mosquitoes. Australia is to become the testing ground for a novel strategy.
The outbreak of Zika virus in Brazil had Australian travellers on alert but transmission is only possible in tropical Queensland.
New research shows common local mosquitoes aren’t able to spread Zika. This means Australia is unlikely to see a major outbreak of the disease. But a risk remains in northern Queensland.
A boy is vaccinated during an emergency campaign against yellow fever in the Democratic Republic of Congo.
The massive yellow fever vaccination campaign highlights why existing programmes need to be strengthened.

There is no vaccine to prevent or medicine to treat the chikungunya virus infection. The only available method of prevention is through shielding people from mosquito bites.
Controlling mosquitoes has a large effect on controlling the diseases they carry.
Innovations targeted at mosquito control are good but should not draw focus away from the tried and tested public health measures to control mosquito-borne diseases.
Academics have sent an open letter to the World Health Organisation calling for the Olympics to be postponed or moved because of the Zika threat. They're overreacting.

Angola's yellow fever outbreak has been declared a grade 2 emergency by the World Health Organisation.
The link between microcephaly in unborn children and Zika hasn’t been definitely confirmed, but vaccine development is a top priority.
As Zika fear rises, people are inevitably asking why we don't have a vaccine to protect against the mosquito-borne virus.
Municipal workers wait before spraying insecticide to prevent the spread of Aedes aegypti mosquito at Sambodrome in Rio de Janeiro, Brazil, January 26, 2016.
Zika was discovered almost 70 years ago, but wasn't associated with outbreaks until 2007. So how did this formerly obscure virus wind up causing so much trouble in Brazil?
Why do mosquitoes not suffer from the infections they pass on?
There's something about mosquitoes that means they don't get sick from the infections they carry. So can we turn that function off, genetically?
Spread by mosquitoes.
Could this relatively unknown virus become a household name in the Americas in the year to come?
Which way to the bar?
The UK's recent heatwave is perfect for mosquito breeding but something far more dangerous may be coming.

Of the dangers facing travellers to Brazil for the World Cup, yellow fever is one of the least likely to pose a real threat. But there are two important things to know about the illness. First, it’s a…
